Are you looking for more efficient ways to design your consumer tests to uncover drivers of liking and optimise your products?

This workshop will give you an overview of how experimental design techniques can be adapted to help you optimise components of products, processing and packaging using responses collected from sensory and consumer panels. There are many different software tools which help with this, creating the experimental sample designs and providing graphical analysis to aid interpretation of the results. We will use Design Expert ( and there will be opportunities for you to “play” with the software and evaluate its ease of use and functionality.

Workshop Outline

  • Motivation for use of structured sample designs.
  • Finding the key influences on consumer liking and sensory characteristics and uncovering interactions between ingredients and process parameters.
  • Using these key parameters to plan further studies to optimise and predict liking.
  • Dealing with more difficult problems -investigating the complete recipe or mixture.
  • Visualisation of the response surfaces, simultaneous optimisation of several performance measures including cost.


Anne Hasted began her career as an academic statistician at Reading University, leaving in 1989 to set up Qi Statistics Ltd offering statistical training and consultancy support to research and industry. She has wide training and consultancy experience in the food industry, particularly in the area of product improvement.



Motivation for using structured designs: benefits, clarity, efficiency


Factorial Designs – experimenting on several process or product components simultaneously. Interpretation of results, importance of understanding interactions.




Workshop – graphical interpretation of effects


Application to sensory profile data and consumer test data.


What can you do if there are too many samples for an achievable experiment? Compromises and risks.




How and why of Optimisation designs
Case Study examples optimising recipes and processes under cost constraints


Workshop on joint optimisation for recipe and cost




Working in constrained spaces -mixture designs. Graphical interpretation
